In this embodiment, the third wireless communication unit 200 and the fourth wireless communication unit 220 can form wireless communication. In addition, the communication protocol between the first wireless communication unit 104 and the second wireless communication unit 124 is different from the communication protocol between the third wireless communication unit 200 and the fourth wireless communication unit 220. For example, if the first wireless communication unit 104 and the second wireless communication unit 124 comply with the Bluetooth communication protocol, the third wireless communication unit 200 and the fourth wireless communication unit 220 can conform to the wireless local area network protocol or the infrared communication protocol. If the first wireless communication unit 104 and the second wireless communication unit 124 comply with the wireless local area network communication protocol, the third wireless communication unit 200 and the fourth wireless communication unit 220 may conform to a Bluetooth communication protocol or an infrared communication protocol; analogy. It should be noted that the components of the same reference numerals as those shown in FIG. 2 in FIG. 3 have substantially the same principle of operation, and are not described herein again.

After the remote controller 20 and the display device 22 complete the pairing via the above manner, the remote controller 20 can control the display device 22 via the third wireless communication unit 200 and the fourth wireless communication unit 220. In other words, in this embodiment, the remote controller 20 and the display device 22 can be paired with the second wireless communication unit 124 via the first wireless communication unit 104, and then executed by the third wireless communication unit 200 and the fourth wireless communication unit 220. The function that the user operates. The present invention can replace the display device 12a-12e with the display device 22.

Please refer to FIG. 4. FIG. 4 is a functional block diagram of the remote controller 10 and the display device 32 according to another embodiment of the present invention. The main difference between the display device 32 and the display device 12a-12e is that the memory unit 126 of the display device 32 further stores a complete function table 320 and a dummy function table 322, and the ID code is stored in the memory unit 126. . In this embodiment, the first wireless communication unit 104 and the second wireless communication unit 124 are in accordance with an infrared communication protocol, and the identity code ID may be a serial number of the display device 32. The serial number described above is the exclusive number assigned by the manufacturer to the display device 32 when the display device 32 is shipped. Further, the full function table 320 records the scan code corresponding to the broadcast request key 1020 and the plurality of remote control functions, and the dummy function table 322 records the scan code corresponding to the broadcast request key 1020. In other words, in addition to the scan code of the broadcast request key 1020, the fields of the other scan codes of the dummy function table 322 are blank (ie, undefined).

The present invention can replace the display device 12a-12e with the display device 32. The manner in which the remote controller 10 and the display device 32 are paired is substantially the same as the manner in which the remote controller 10 is paired with the display devices 12a-12e, and details are not described herein again. In this embodiment, the display device that is paired with the remote controller 10 responds to the control signal sent by the remote controller 10 according to the full function table 320, and the display device that is not paired with the remote controller 10 responds to the remote controller 10 according to the dummy function table. The control signal sent. Therefore, when the display device 32 and the remote controller 10 complete the pairing, the remote controller 10 can control the display device 32 to perform the function operated by the user via the first wireless communication unit 104 and the second wireless communication unit 124 according to the full function table 320. On the other hand, when the display device 32 is not paired with the remote controller 10, since the fields of the other scan codes of the dummy function table 322 are blank, even if the display device 32 receives the control signal from the remote controller 10, the display is displayed. Device 32 also does not perform any function.

Please refer to FIG. 5. FIG. 5 is a functional block diagram of the remote controller 40 and the display devices 12a-12e according to another embodiment of the present invention. The main difference between the remote controller 40 and the remote controller 10 described above is that the input unit 102 of the remote controller 40 further includes at least one group setting button. In this embodiment, the input unit 102 of the remote controller 40 includes two group setting keys 400, 402. It should be noted that the number of group setting keys can be determined according to the actual application, and is not limited to two. The group setting keys 400, 402 are used to set a display device that is paired with the remote controller 10.

For example, the user can set the display device 12a to be paired with the remote controller 10 by using the group setting button 400 in the above manner, and set the display devices 12b, 12c, and 12d to be paired with the remote controller 10 by the group setting button 402 in accordance with the above manner. When the user wants to control the display device 12a with the remote controller 10, the user only needs to trigger the group setting button 400, and the above-mentioned pairing operation need not be performed again. Similarly, when the user wants to control the display devices 12b, 12c, and 12d by the remote controller 10, the user only needs to trigger the group setting button 402, and the above-described pairing operation need not be performed again.

Taking FIG. 1 as an example, the user can press the group setting button 400 after inputting "001" to the input key 1022 of the remote controller 10 to complete the pairing of the remote controller 10 with the display device 12a. In another embodiment, the user may first press the group setting button 400, operate the input button 1022 of the remote controller 10 to input "001", and wait for a predetermined time (for example, three seconds, five seconds, etc.) to enable the remote control. The device 10 automatically completes pairing with the display device 12a. The operation mode of the group setting key 402 is the same as that of the group setting key 400, and details are not described herein again.

When the group setting button 400 is triggered, the display device 12a that is paired with the remote controller 10 can emit sound, light, and/or projection to allow the user to confirm the display device 12a that he or she desires to control. Similarly, when the group setting button 402 is triggered, the display devices 12b, 12c, 12d that are paired with the remote controller 10 can emit sound, light and/or projection to allow the user to confirm the display device 12b to be controlled. , 12c, 12d.

Please refer to FIG. 6. FIG. 6 is a schematic diagram of a wireless pairing system 1' according to another embodiment of the present invention. The main difference between the wireless pairing system 1' and the wireless pairing system 1 described above is that the display devices 12a-12e of the wireless pairing system 1' are televisions. Therefore, in this embodiment, when the broadcast request key 1020 of the remote controller 10 is triggered, the display devices 12a-12e directly display the identity code ID on its display unit 122.

In summary, when the user wants to pair the remote controller with the display device, the user can first trigger the broadcast request button of the remote controller to send the broadcast request signal to the display device. When the display device receives the broadcast request signal, the display unit of the display device displays the identity code.
